# Configurar Swagger UI

Você pode configurar alguns <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">parâmetros extras da UI do Swagger</a>.

Para configurá-los, passe o argumento `swagger_ui_parameters` ao criar o objeto de aplicativo `FastAPI()` ou para a função `get_swagger_ui_html()`.

`swagger_ui_parameters` recebe um dicionário com as configurações passadas diretamente para o Swagger UI.

필요에 따라 응용 프로그램이 시작되기 전이나 종료될 때 실행되는 이벤트 핸들러(함수)를 정의할 수 있습니다.

이 함수들은 `async def` 또는 평범하게 `def`으로 선언할 수 있습니다.

/// warning | "경고"

이벤트 핸들러는 주 응용 프로그램에서만 작동합니다. [하위 응용 프로그램 - 마운트](./sub-applications.md){.internal-link target=_blank}에서는 작동하지 않습니다.

///

## `startup` 이벤트

응용 프로그램을 시작하기 전에 실행하려는 함수를 "startup" 이벤트로 선언합니다:

```Python hl_lines="8"
{!../../docs_src/events/tutorial001.py!}
```

Именно поэтому, FastAPI сам предоставляет альтернативную документацию API (используя ReDoc), которую можно получить по адресу: <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.
